VALVE-CONTROLLING MEANS.

Application filed November 3, 1921. Serial No. 513,440

This invention relates to im rovements in valve controlling means, an particularly to means for controlling the valves associated with the respective discharge pipes leading from the several compartments of an oil delivery tank vehicle.

In the delivery of oils and gasoline a large tank subdivided into a plurality of independent compartments is ordinarily employed, the tank being mounted on a vehicle. Discharge pipes extend outwardly from the bottom of each compartment to a point of dischar e usually at the rear of the vehicle, valves eing provided adjacent the outlet ends of the respective pipes for controlling the discharge of the contents of the several compartments. Any damage to one of the til discharge pipes permits the contents of the compartment connected with that particular pipe to leak out. It is one of the objects of this invention to provide valves associated with the inlet/ends of the respective discharge pipes so that said pipes may be cut ofl at all times except when it is desired to draw ed the oils or gasoline.

A further object of the invention is to provide means, preferably in the form of a reciprocably mounted member, which is so connected to the respective valves that all of the valves may be manipulated simul taneously from an external point.

In its preferred form the invention contem lates a member reciprocably mounted on t e top of the tank in combination with links which extend through the tops of the respective compartments and are operably connected with the respective valves; and a further object of the invention is to provide a cam connection between the operating member and the several links so that the valves may be conveniently and easily raised or lowered, as desired.

()rdinarily, the several discharge pipes terminate in a cabinet usually located at the rear of the vehicle which cabinet serves as a place in which to carry the oil cans and funnels commonly used; and a further object of the invention is the provision of an operating lever mounted in said cabinet which controls the manipulation of the respective valves inside of the several compartments and which is so arranged that the lever must be moved to a position to close all the valves before the door of the cabinet can be closed, thus insuring that the delivery man will close all the valves inside of the compartments before starting the vehicle.

The invention consists in the novel constructions, arrangements and devices to be hereinafter described and claimed for carrying out the above stated objects and such other objects as will appear fromthe following descri tion of a certainpreferred embodiment illustrated in the accompanying drawings, wherein- Fig. l is a side elevational view of a fragmentary portion of a tank equipped with valve controlling means embodying the principles of the invention;

Fig. 2 is a longitudinal sectional view through one of the compartments of the tank, on an enlarged scale, showing the connection between the valve located in the bottom of the compartment and the contank 5 adapted to be mounted upon a suitable vehicle (not shown) and consisting of a plurality of independent compartments 5. A cabinet 6 is preferably mounted on the rear of the tank and is provided with a door 7. Discharge pipes 8 lead from the bottom of the respective compartments 5 and preferably terminate in the cabinet 6. In the discharge end of each pipe is located a shut-off valve (not shown), as is customary to control the flow of oil when drawing it ed for the customer. 7

In the bottom of each compartment is provided a nipple 9 which is externally welded or otherwise secured to, bottom of the compartment to provide an oil-tight joint. A gland 10 is threaded into the nipple 9 and is provided with a valve seat 11, the inlet end of the discharge pipe 8 being threaded into said gland. The valve 12 normally rests upon the seat 11 being held tightly thereagainst by a spring 13 which is interposed between the upper side of said valve and the under side of an open bonnet 14 preferably formed integrally with the gland l0.

ill)

In the top of each compartment and in alignment with the valve 12 is provided a nipple 15 which is externally welded or otherwise tightly secured to the top of the compartment. The nipple 15 is internally threaded for the reception of a pair of opposed perforated glands 16 through which a rod 17 extends, packing material 18 preferably being interposed between the glands 16 around the rod 17 to provide an oil tight connection. A plurality of adjustably connected links 19 connect the lower end of the rod 17 with the stem 12 of the valve 12.

Over each of the rods 17 is positioned an inverted U-shaped bracket member 20 the legs of which are secured in any desired manner to the upper and outer side of the tank. The cross portion 20 of each bracket member is provided with a slot 21 in which a U-shaped member 22 may reciprocate vertically, said member being connected to the upper end of the rod 17. An operating member, designated as a whole by the reference character 23, consisting of a plurality of flat faced blocks 24 adjustably connected together by rods 25, extends lengthwise over the top of the tank, said blocks 24 being between the upstanding legs of the U-shaped members 22 and slidably engaging the cross bars 20 of the brackets 20, respectively. The blocks 24 are each provided with an obliquely extending cam slot 26 the upper end 26 thereof extending substantially horizontally. A bolt 27 carried by each of the members 22 extends through the cam slot 26 c of the associated block 24.

It will now be apparent when the operating member 23 is 1n the position shown in the drawings that the bolts 27 are in the lowermost portions of the respective cam slots 26 and the several valves 12 are held tightly against their respective seats by the springs 13. When the operating member is moved forwardly over the brackets 20, the bolts 27 will be forced to travel upwardly in the cam slots thereby simultaneously raising the several valves from their respective seats. If the operating member 23 be pushed forward sufficiently to bring the bolts into engagement with the horizontal portions 26 of the cam slots, the valves will be locked in open position.

In order to facilitate manipulation of the valves 12, an operating lever 28 is pivotally mounted to the top of the cabinet 6 and is connected at its upper end to the rear end of the operating member 23. It will be noted that said lever 28 is so arranged that it can only be moved to thrust the operating member 23 forwardly to open the valves 12 when the door 7 of the cabinet is open. In other words, the operating lever 28 must be substantially in the position shown in Fig. 1, before the door of the cabinet may be closed, in which case the valves 12 are all closed. This arrangement reduces to a minimum the likelihood of the delivery man starting off without shutting all the valves 12, it being customary to place the measuring cans and funnels in the cabinet and close the door thereof before driving away.

I claim:

1. The combination with a tank having discharge pipes and valves located in the tank and controlling the flow through said ipes, of brackets mounted on the tank, inks slidably mounted in said brackets and projecting into the tank, adjustable links connecting said first mentioned links with said valves, a reciprocably operating member mounted on the tank and having independent cam slots, and pins carried by said links and extending into said slots to simultaneously control said valves.

2. The combination with a tank having discharge pipes and valves located in the tank and controlling the flow through said pipes, of brackets mounted on the tank, links vertically slidable in said brackets and projecting into the tank, adjustable threaded members connected to the links, chain links connecting the threaded members to said valves, and operating member horizontally reciprocable on said bracket and having an independent cam slot for each vertical link, and pins carried by said vertical links and extending into said slots to simultaneously control said valves.

In testimony whereof, I atlix my signature.

ARTHUR BORCHARDT.
